我们观察到在2 μ m泵浦的纳米尖峰硫族化物-二氧化硅混合波导中产生的超连续谱的相干性。超连续谱被证明是相干的泵，通过干涉它与一个双共振光参量振荡器（OPO），这本身是相干的共享泵浦激光。这使得OPO能够相干锁定到光学参考泵浦频率梳，从而产生波长为1至6 μ m的复合频率梳。(C)2014年美国光学学会
We observe the coherence of the supercontinuum generated in a nanospike chalcogenide-silica hybrid waveguide pumped at 2 mu m. The supercontinuum is shown to be coherent with the pump by interfering it with a doubly resonant optical parametric oscillator (OPO) that is itself coherent with the shared pump laser. This enables coherent locking of the OPO to the optically referenced pump frequency comb, resulting in a composite frequency comb with wavelengths from 1 to 6 mu m. (C) 2014 Optical Society of America
